The dispatcher then asks Yvonne where her children and husband are and she reveals that Zachary made it to the garage and was trying to blow the car horn to get their neighbor's attention to the house.

Police released a 911 call made by Yvonne Ervin, who told the dispatcher, 'Please send someone to my house. My children are trying to kill me. They've attacked me and my husband'

Police said they found blood and broken furniture throughout the house (pictured) and also believe the brothers' tampered with the gas line to start a fire

She then tells the dispatcher the names and ages of her sons before revealing her sons are armed.

'They have a shotgun,' she said. 'We have a shotgun and a pistol in the house and I can't find my pistol so I'm assuming they've taken it - and they have his shotgun.'
